Enzymatic treatment of whey proteins in cow's milk results in differential inhibition of IgE-mediated mast cell activation compared to T-cell activation.

Background: Cow's milk (CM) hydrolysates are frequently used as milk substitutes for children with CM allergy. In hydrolysates, allergenic epitopes within CM proteins are diminished by enzymatic treatment. The aim of this study was to examine the allergenic and immunogenic properties of whey proteins during hydrolysis.

Supplementation with a fish oil-enriched, high-protein medical food leads to rapid incorporation of EPA into white blood cells and modulates immune responses within one week in healthy men and women.

Immune modulatory effects of EPA and DHA are well described. However, these fatty acids must be effectively incorporated into cell membrane phospholipids to modify cell function. To address the absence of human data regarding short-term incorporation, the present study investigated the incorporation of EPA and DHA into white blood cells (WBC) at different time points during 1 wk of supplementation with a medical food, which is high in protein and leucine and enriched with fish oil and specific oligosaccharides.
